That crocodiles share a common ancestor with bird dolphins and dog support your answer?
Crocodiles and birds share a common ancestor. This can be seen by comparing the internal anatomy of the two. Dogs and Dolphins also have a common ancestor. Their skeletons again are both distinctly mammillian. The ancestor of dogs and dolphins and the ancestor of birds and crocodiles will again share a common ancestor, but you will need to go much further back. I am not sure of the timescales but we are talking tens to hundreds of million years.
